SNOW-PLOW FOR RAILROADS.

SPECIFICATION forming part of Letters Patent N0. 782,149, dated February'7, 1905.

Application filed June 24, 1904. Seria No. 213,998-

1'0 (077 117mm, it may concern/.-

Be it known that I, EDWARD J on): LITT, of Dublin, in the county ofPerth, Province of Ontario, Canada, have invented certain new and usefulImprovements in Snow-Flows for Railroads, of which the following is aspecilication.

My invention relates to improvements in snow-plows for railroads; andthe objects of my invention are to devise a snow-plow to be driven infront of a locomotive in order to raise the snow from the tracks andthrow it outwardly over the banks along the sides of the road asufficient distance to prevent its sliding back and obstructing therailway, further objects being to make the device such that it cannotchoke and to make it cheap and simple in construction; and it consists,essentially,of a suitable truck having a downwardlysloping flat-endedscoop at the forward end thereof, said scoop having side walls suitablyconnected thereto, and braced and curved converging wings located on thetop of the truck and adapted to throw the snow off to the sides, thevarious parts of the device being constructed and arranged in detail, ashereinafter more particularly described.

Figure 1 is a perspective View of the plow. Fig. 2 is a side viewthereof.

in the drawings like letters of reference indicate corresponding partsin each ligure.

1/ is the body of the truck, the top of which is at a suitable height,but preferably at about the height of the highest snow banks or driftswhich are likely to form alongside of the track. At the forward end ofthe truck 11 a scoop b is provided, which consists of thedownwardlysloping portion 0, the lower end of which is terminated in aknife-edge (I at or very close to the level of the rails and the sidewalls c e, which flare outwardly to a slight extent and are adapted tocut out the sides of snow through which the plow is cutting its way. Thescoop 7) extends upwardly to the top of the truck a or thereabout andhas at its upper end a pair of converging wings ff, meeting in aninwardly-curved line g. These wings are concave, and their generaldirection is an outward and rearward slant. By means of suitablebracingrods /1. or the like the wings are held rigidly in their properposition, and similarly the side walls 0 are braced by means of thebracing-rods and the continuous strip j, which is secured to the sidewalls e and forms the intermediate arch Z, to which the rods 1' arerigidly secured. The opposite extremities of these rods are securedpreferably to the wings f, where they intersect.

Underneath the lower portion of the scoop 7/ I may provide an auxiliarys1rpporting-wheel journaled in suitable bearings 11), theobject of thiswheel being obviously to assist in supporting the forward part of thescoop. Auxiliary knives n are also provided and may be formed integralwith or suitably secured to the side walls w, these knives extendingforwardly from the bottom of the walls 1 to the edge of the knife (I.

The mode of operating my invention is as follows: The locomotive havingbeen attached to the end of the truck, the plow is driven preferably atas high a rate of speed as possible along the track which is to becleared of snow. The result will be that when the lower edge of thescoop comes in contact with the snow it will be forced up the slopingportion 0 at a very rapid speed, owing to the rate at which the plowtravels, and then will be thrown with great force outwardly to the sidesof the track by means of the wingsf'f'. It is to be particularly notedthat on account of the sloping part c and the height of the upperportion of the same the snow will be raised higher than the top of anyordinary drifts before it is thrown outwardly, and consequently itcannot fall back again into the cutting, but will be thrown to adistance of in the neighborhood of twenty feet or more from the track.

It will now be seen that l have invented a snow-plow for railway usewhich has considerable advantages over plows previously used.

lam aware that plows have been constructed with sloping portions toraise the snow and deflecting portions or wings to throw it outwardly;but in all such plows of which 1 am aware the deflecting portionextended down to within a very short distance of the bottom of theraising portion, and the result was that when the plow was forced into adrift of considerable height the snow would not be raised sulficientlyhigh to be thrown clear of the banks at the sides, but would jam betweenthe banks and the deflecting-Wings, so that before the plow could getvery far into such a drift it would be completely choked. From the abovedescription, however, it will be readily seen that my device overcomesthis difliculty. The side knives or walls of the scoop 6 cut clean intothe drift, and the snow is raised by the impetus of the plow to asufficient height to be thrown entirely clear of the banks of snow atthe sides of the track.

It is to be understood that in manufacturing my plow certain changes inthe details of construction may be made without departing from thespirit of my invention-such, for instance, as the substitution ofdifferent forms of bracing-rods or a different kind of truck, &c. Itherefore do not Wish to be limited in the scope of my patent to theprecise con.

struction which I have shown and described herein.

l/Vhat I claim as my invention is A snow-plow, consisting of a truck, aclownwardly and forwardly extending scoop secured to the front portionthereof and semicircular deflecting-wings secured horizontally to thetop of the truck, said Wings meeting at the top of the scoop andconverging outwardly toward each side of the truck, substantially asdescribed.

Signed at Mitchell, in the Province of Ontario, this 1st day of April,1904.
